HOOF-TRllVlMING NIPPERSI.

SPECIFICATION forming part of Letters Patent No. 728,856, dated May 26, 1903. Application filed May 19, 1902. Serial No.107,898. (No modeh) To aZZ whom it may concern: arounded end or abutment a while the other Be it known that I, JOHNM. BRYANT, a citiis provided with a knife I). The rounded zen of the United States, residing at Minnehead a of the one jaw is provided with a apolis, in the county of Hennepin and State block or face section 0, of copper or other 5 of Minnesota, have invented certain new and metal which is softer than iron, so as to preusefullmprovementsin Hoof-Trimming Nipvent the dulling of the edge of the knife 5 pers; and I do hereby declare the following when the cutting edge of the latter is forced to be a full, clear, and exact description of against the same. The knife I) is curved the invention, such as will enable others slightly from end to end, such curve being 10 skilled in the art to which it appertains to approximately an arc struck from the center make and use the same. of the pivot a. Said knife works endwise in My invention has for its object to improve a channel-like seat a", formed in the jaw, to the construction of farriers trimming-nipwhichit is applied. A short nutted bolt Z) pers, used for trimming the hoofs of horses; is passed through the butt-end of the tool b [5 and to this end it consists of the novel deand through a slot a in the jaw 0, This vices and combinations of devices hereinafter nutted bolt b serves to clamp the knife I) in described, and defined in the claim. its set adjustment; but to adjust the said The invention is illustrated in the accomknife and positively prevent endwise movepanying drawings, wherein like characters ments thereofI provide a set-screwf, which is 20 indicate like parts throughout the several screwed throughalugct oftheknife-equipped views. jaw and impinges against the butt-end of the Figure l is a plan view of a pair of trimsaid knife.. When the knife is properly set, ining-nippors embodying my invention, some it will engage with the central portion of the parts being broken away.

In view of the curved As is usual, these nippers involve a pair of form of the knife, further, in view of the 5 strong levers a, pivotally connected at a, and rounded form of the end or abutment of the provided with jaws a Thejaws a are thickjaw which cooperates with the said knife, and ened up or made wider than the levers a, so also in view of the curved form given to the that they leave shoulders a as best shown in levers a, whereby the jaws may be very widely Figs. 1, 2, and 5. At the extreme open posiopened, the tool is adapted for classes of work 40 tion of the levers a and jaws a the shoulders which pliers of this character as hitherto a will strike against the said levers and limit provided would not perform. such movements. To make it possible to This tool was especially designed for use in open the jaws much wider than usual in detrimming horses hoofs and particularly for vices of this character, I curve the levers a, gouging out'the bottom of the hoof betwee 45 as indicated at a, so that the said shoulders the frog and the rim thereof. 5 a will fall back into the depressions afforded In Fig. 5 a portion of a horses hoof is inthereby, and thus permit the jaws to be very dicated by dotted lines marked 2, z being the widely opened, as indicated in Fig. 5. frog of the hoof and .2 the rim. It will be The jaws a are bowed or curved in reverse here seen that when the rounded end or 50 directions, and one thereof is provided with abutment a of the one jaw is placed against 1 0 the outside rim of the hoof it serves as a sliding or rolling base of resistance for the knife b, and it will also be seen that the said knife, when the levers a are closed together from the position indicated in Fig. 5, will gouge or cut into the bottom of the hoof, not abruptly inward, as would be the case with a straight knife, but with a gradual curve, serving to but slightly concave the hoof. It will also be noted that in the use of the tool the jaws a must be very widely opened. It is of course evident that the rounded end or abutrnenta may be pressed against the frog 2 of the hoof and the knife I) be made to cut inward from the rim of the hoof toward the frog.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

The combination with the levers a pivoted at a, and provided with the curved jaws 013, one of which jaws terminates in the rounded abutment a and the other of which has a channel-like knife-seat a and slot a of the knife 1) working in said seat a, and curved approximately in the'line of an arc struck from the pivot a, a set-screw working through a part of one of said jaws and adjusting said knife, and the nutted bolt 1) passed through said knife and said slot a and clamping said knife in its set position, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

JOHN M. BRYANT.
